Yes, call Don at AFP and see if you should use something like his FM-200 vs the FM-150. The latter is typical for O-320-360, 150-185 HP and the former is typical for ~200 HP engines and up.
He also has options for mounting the servo horizontally on a vertical sump, which is typical on 6 cyl rockets. I have the horizontal setup on my O-360-A4M with vertical sump.
